Eufy PoE Bullet-PTZ Cam S4

Three Lenses, 360° Coverage — 4K Surveillance That Tracks Everything

The eufy PoE Bullet-PTZ Cam S4 packs a 16MP triple-lens system into one housing: a 4K wide-angle bullet camera watches the full scene across a 122° fixed view, while the 2K PTZ lens below pans 360° and zooms up to 8× (hybrid) to lock onto and follow subjects. When the bullet lens spots movement, the PTZ automatically frames and tracks the subject in sharp close-ups from as far as 164 ft — and with two Bullet-PTZ cameras, live cross-cam AI tracking hands subjects off between them seamlessly.

AI recognition distinguishes people, vehicles, pets, and strangers to cut false alerts dramatically, while Starlight color night vision with AI-ISP processing captures vivid color footage after dark without needing a constant spotlight. HDR is enabled by default, preserving fine details like license plates in harsh or mixed lighting. When suspicious activity is detected, an active deterrence system fires smart sirens and red-and-blue strobe lights.

A single Ethernet cable carries both power and data (PoE) for reliable 24/7 recording through your eufy NVR — the S4 Max system scales to 16 channels and up to 16TB of storage. Full-duplex two-way audio with AI noise reduction handles conversations clearly, and the IP65 weatherproof build keeps it running outdoors year-round. Note: this is an add-on camera that requires a eufy NVR to operate.
